FIELD: electrical communication.
SUBSTANCE: invention relates to electrical communication. Initial information sequence of symbols for transmission is generated, a code sequence of symbols is formed from it by noise-immune block modular coding, encrypting a code sequence of symbols and subsequent controlled symbol rearrangement is performed, an encrypted sequence of symbols is sent to a communication channel. At the receiving side with the received encrypted symbol sequence, symbols are rearranged and decrypted, a code sequence of symbols is obtained, consisting of information and first verification sequences of symbols, based on which the second verification sequence of symbols is formed. Obtained first and formed second verification sequences of symbols form a syndrome sequence, structure of which enables to detect errors in the received sequence, determine their multiplicity and conclude on presence of simulating actions of an intruder.
EFFECT: technical result is high stability of transmitting information to intentional simulating actions of intruder interference.
